Concerning an optical information recording medium that can optically record and reproduce the phlegm, while preventing the foul odor peculiar to T-compounds generated by irradiation with energy beams such as light and heat,
Concerning optical information recording media with high sensitivity and long life (e*) [Prior art and its problems] Conventionally, optical fishing rods have been formed on a base IIl as shown in figure s1, and are circular. There is a method in which a 24C energy beam is irradiated to form a 9-bit string 1 corresponding to the information to be distributed.

If a material consisting of C and H is successfully obtained, it can be obtained by sputtering using Te as a target in a gas that combines C and H, such as a mixed gas of methane (CH,) and argon (Mr). It will be done. Here, the 4idk content of C and H in TegA can be freely controlled by the mixing ratio of CH4 and Mr and the applied high local aI-force. 3W/
When a high frequency (13.56 MH1) power of d is applied between the Te target and the group 1[11, it is possible to form 9- containing C in an atomic ratio of 0.2 to 're.

Here, the H content can be arbitrarily selected as long as the film does not contain so much IIVc that hydrogen gas (Hl) is generated. Furthermore, since the film thickness is proportional to the sputtering time, it can be freely controlled.

P, 699 (1981) K: Show Me! is also excellent. In other words, according to this document, the airtight seal is intended to shield the short-lived Te + sea bream from the atmosphere, but with the structure of the species, it is impossible to completely shut off the atmosphere, so it is necessary to extend the lifespan. It's not very useful for humanity. However, in the present invention, the airtight seal is not used to prevent air from entering, but rather to prevent a small amount of steam from leaking into the air within the airtight seal. Since the test tube itself has a long lifespan of 40 minutes in contact with the atmosphere, it is not necessary to completely pass through the atmosphere.

The rLi shown in 981) is also superior to that of 9. That is, the organic film #ais in this document is for preserving the l+0 set of Tanjukan from outside air, but a porous organic film is insufficient for that purpose. However, in the present invention, only the rounded K is formed to catch a small amount of vapor when pits are formed.) Since the recording film 12 itself has a long life in the present invention, it is significantly superior to that of the above-mentioned document.
